WASHING- MACHINE.

SPECIFIGATION forming part of Letters Patent No. 475,339, dated May 24,1892.

Application filed November 28, 1891. Serial No. 413,446. (No model.)

T0 at whom it may concern.-

Be it known that I, JOSIAH J. OTTO, a citizen of the United States,residing at Altoona, in the county of Blair and State of Pennsylvania,have invented certain new and useful Improvements in \Vashing-Machines;and I do hereby declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it pertains tomake and use the same, reference being had to the accompanying drawings,which form a part of this specification, in which- Figure 1 indicates aplan view of my improved washing-machine. Fig. 2 is avertical sectionthrough line 00 0c of Fig. 1. Fig. 3 is an enlarged detail of the upperinner end of the inclined standards. Fig. 4 is a sectional View throughline to w of Fig. 5. Fig. 5 is an elevation of the inner face of beveledwheel out of engagement with crank-shaft. Fig. 6 is same of oppositewheel through line cc of Fig. 2, showing same in engagement with shaft.Fig. 7 is a horizontal section on line y y of Fig. 2.

My invention relates to washing-machines; and my object is to produce amachine adapted to impart a constant rubbing motion to the clothes,applied in opposite directions alternately, and at the same time todischarge numerous jets of water against said clothes with considerableforce; and to this end I employ the device hereinafter more specificallydecribed, and which consists of a suitable vessel preferably wider atthe top than at the bottom and provided with series of rollers ournaledin the sides and bottom thereof, a perforated cylinder suspended in saidvessel from a hollow shaft and adapted to be rotated in oppositedirections alternately by said shaft, and a piston having a plungeradapted to be operated vertically in said cylinder, whereby the watercontained therein is impelled through said perforations against theclothes contained in said vessel with considerable force.

I will now describe my invention, reference being had to theaccompanying drawings, forming part hereof, in which like figuresindicate like parts wherever they occur.

Referring to said drawings, 1 is a vessel preferably of greater width atthe top than at the bottom and provided with series of rollers 2 2 2 2,&C., formed of any suitable material and j ournaled in the sides andbottom thereof. as shown in Figs. 2 and 7.

3 is a cylinder, convex or bulging at the bottom and having numerousperforations therein and in its sides and provided with nozzle-likeextensions 4 4 4 4, projecting from the sides thereof near the upper endof the same. Said cylinder is bolted or otherwise suitably secu red tothe lower end of the hollow vertical shaft 5, which projects into saidvessel and is supported in the bearing 6 in the frame 7, secured uponthe top of said vessel, as shown in Fig. 2.

8 is a horizontal beveled wheel suitably secured upon the upper end ofsaid shaft and adapted to receive motion from the beveled wheels 9 and10, which are loosely secured upon the crank-shaft 11, meshing with saidhorizontal wheel at opposite sides of the same.

Said crank-shaft is suitably journaled in bearings 12 and 13,respectively, in the uprights or standards 14, which are secured uponsaid frame at either end thereof, the upper inner faces of saidstandards being provided with inwardly-projecting inclined and curvedflanges for the purpose hereinafter specified.

15 is a large spur-wheel suitably secured upon one end of saidcrank-shaft and adapted to mesh with and receive motion from the smallspur-wheel 16, secured upon the short horizontal shaft 17, which isjournaled in bearings 18 and 19 in the lower end of one of saidstandards 14 and the upper end of the standard 20, respectively, theouter end of said short shaft being provided with the hand-crank 21.

.22 is a connecting-rod secured to the crank upon the shaft 11, thelowerend thereof being pivotally attached to a piston-rod 23, projectingthrough an orifice in the center of said horizontal beveled wheel,through said hollow shaft 5, and into said cylinder, the lower endthereof having secured thereto the head or plunger 24 and adapted tovertically reciprocate the same in said cylinder, whereby the watertherein may be discharged through the perforations in the bottom andsides of said cylinder with great force against clothes contained insaid vessel. Rigidly se- IOC cured to said horizontal shaft at eitherside of the crank thereon and projecting vertically in oppositedirections therefrom are arms 25 25, having formed therein near theirouter ends recesses 26 26 for the reception of pins 27 27, freelymovable therein, the heads of said pins being of greater cross-sectionthan the shanks thereof, upon which are mounted the spiral springs 2929, which when compressed, as hereinafter specified, permit the shanksof said pins to project through and operate freely in orifices in theinner face of said arms opening from said recesses. The beveled wheels 9and 10 are provided with corresponding recesses 30 30 for the receptionof pins 31 31, similar to those recessed in said arms 25, the shanksthereof, however, being reversed and projecting in orifices in the outerface of said wheels. It is obvious that the rotation of said wheels 9ld'brings the pins 31 31, recessed therein, respectively, in contactalternately with the inclined and curved inner faces of the standards 1414, thereby forclng the pins 27 27, recessed in the arms, alternatelyout of the recesses in said wheels and releasing said wheels alternatelyfrom engagement with said arms, the recoil of the springs mounted uponthe inner ends of the pins 27 27 forcing the same into the recesses ofthe wheels when opposite said recesses, thereby rotating the shaft andperforated cylinder attached thereto one-half revolution alternately inopposite directions.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

1. In a washing-machine, substantially as forated cylinder, a hollowvertical shaft carrying a beveled wheel provided with an orifice throughthe center of the same, a crankshaft suitably secured in bearings, avertical piston rod suitably secured thereto and adapted to bevertically reciprocated in said hollow shaft and said cylinder, armsrigidly secured on said crankshaft at either side of said crank andprojecting in opposite directions therefrom and provided with recessedpins carrying spiral springs mounted thereon, and a pair of beveledgear-wheels secured upon said shaft in close juxtaposition with saidarms and havingsimilar recessed pins with said arms and adapted to bethrown into clutch with said arms alternately, substantially as and forthe purpose herein set forth.

In testimony that I claim the foregoing I hereunto atfix my signaturethis 24th day of November, A. D. 1891.
